FAQ

Questions about sap_x402_has_escrow

What does the sap_x402_has_escrow tool do? +

Check whether an x402 escrow exists for an agent/depositor pair. SAP MCP context: Payment and settlement flow. Estimate or fetch state before creating escrows or settling calls; write operations require an enabled signer mode and MCP policy approval. SAP MCP execution guidance: Intent: SAP MCP tool workflow. Pricing: priced by hosted x402 challenge. Routing: paid hosted call; call sap_estimate_tool_cost first, then use sap_payments_call_paid_tool if the runtime cannot handle x402 natively. Signer boundary: hosted reads/builders never receive keypair bytes; value-moving results must be finalized locally when signing is required. It is categorised as a Write tool in the Sap MCP Server, which means it can create or modify data. Consider rate limits to prevent runaway writes.

What parameters does sap_x402_has_escrow accept? +
